Rhododendron disease prevention in Belgium
Physiological lesions in common diseases of Rhododendron in Belgium are mainly caused by differences in the quality of water between production and sales areas, and inadequate temperature during circulation or insufficient illumination in home interiors. The method of treatment is mainly based on the physiological habits of Belgian rhododendrons with good lighting, pH and temperature of irrigation water.
Common pathological diseases include:
Grey mold
The basic measures for remediation are seedling thinning, dehumidification, and heat preservation. Drug treatment may be selected from the group consisting of fluocin (1500-fold solution), mancozeb (500-fold solution), quick-acting (150-fold solution), and chlorothalonil (600-fold solution) fungicides. Generally used 2-3 times, interval 7-10 days once, rotation is better.
White tinea
Bacterial bacteria generally endanger the roots. The cultivation matrix should be strictly selected and precautions such as exposure or mixing should be used before use. Medications can be treated with Enkeson (500x solution) or Pentachloronitrobenzene (800x solution) during rooting. The general application can be eliminated twice, with an interval of about 10 days.
Stem rot
Stalk rot usually occurs on a seedbed, and the symptoms are the rot of the base of the seedling. Transplanting seedlings in time is the fundamental method of governance. Drug control with anti-virus (600 times liquid) or Dubok Kelu (600 times liquid) to root, the effect is better.
The common insect pests are mainly aphids and red spiders, which are sprayed with aphid (1,500 times liquid) or avermectin (3000 times liquid) for drug control. The general spray can be solved 2 times, once in 7-10 days.
